Underpredicted pain disrupts more than correctly predicted pain, but does not hurt more

One of the explanations for the negative effects of underpredicted aversive experiences is that they have more impact than correctly predicted aversive experiences. In a laboratory experiment 40 normal female subjects executed an auditory discrimination task. Subjects were randomly assigned to a correct information condition and an underprediction information condition. After ten trials (baseline) subjects were informed that they would receive some painful (correct prediction) or non-painful tingling (underprediction) stimuli during the discrimination task. Starting just before five of the following 20 discrimination trials, 2 s of painful electrical stimulation was given. Subjects rated sensations and painfulness of the electrical stimulation, subjective anxiety, and degree of distraction from the task, after each pain stimulus. Reaction times of the discrimination task and heart rate were measured. Underprediction information resulted in lower pain ratings, but stronger heart rate responses and higher disruption on the discrimination task, compared to correct information. This suggests that while underpredictions of pain do not hurt more, disruption on primary tasks and physiological impact are higher. Underpredicted pain has more impact than correctly predicted pain, not because it hurts more, but because it conveys inherent danger information.     

Sartre and Bergson: A Disagreement about Nothingness

Abstract

Henri Bergson's philosophy, which Sartre studied as a student, had a profound but largely neglected influence on his thinking. In this paper I focus on the new light that recognition of this influence throws on Sartre's central argument about the relationship between negation and nothingness in his Being and Nothingness. Sartre's argument is in part a response to Bergson's dismissive, eliminativist account of nothingness in Creative Evolution (1907): the objections to the concept of nothingness with which Sartre engages are precisely those raised by Bergson. Even if Sartre's account of nothingness in its entirety is found to be flawed, I argue that the points he makes specifically against Bergson are powerful.

My discussion concludes with a brief examination of the wider philosophical background to Sartre's and Bergson's discussion of nothingness: here I point to some important aspects of Sartre's early philosophy, including some features of his conception of nothingness, that may testify to Bergson's positive influence on his thought.     

The Performance of Hamsters in the Maze Situation Utilizing Gravitation and the Vestibular Sense as Motivation

The hypotheses of this study of sex differences on a measure of self-esteem are as follows: 1) the scales good, nice, generous, pleasant, dependable, honest, and active will group together to form the outer esteem dimension of the semantic differential; 2) the scales strong, leader, powerful, confident, curious, inventive, sharp, and active will group together to form the inner esteem dimension of the semantic differential; 3) males will score significantly higher than females on the inner esteem dimension of the semantic differential; 4) females will score significantly higher than males on the outer esteem dimension of the semantic differential; 5) there will be a significant difference between the scoring patterns of males and females on the two dimensions of the semantic differential after controlling for the effects of race and social desirability. The sample of 442 sixth through eighth grade students consisted of two subsamples made heterogeneous on race, geographic location, and type of school. The Franks-Marolla Self-Esteem Semantic Differential and the Lunneborg and Lunneborg Child's Social Desirability Scale were administered. The findings support each of the hypotheses and indicate that there is a significant difference between the sexes on the Franks-Marolla Semantic Differential Measure of Self-Esteem. It is concluded that additional research in self-esteem might specify the meaning of sex differences in esteem by measuring esteem relative to an individual's structural social positions rather than measuring esteem in the general and environmentally nonspecific contexts as advocated by some.     

From goal motivation to goal progress: the mediating role of coping in the Self-Concordance Model

Abstract

The present studies examined the mediating role of self-regulatory mechanisms in the relationship between goal motivation and goal progress in the Self-Concordance Model. First, a systematic review, using meta-analytical path analysis, supported the mediating role of effort and action planning in the positive association between autonomous goal motivation and goal progress. Second, results from two additional empirical studies, using structural equation modeling, lent credence to the mediating role of coping in the relationship between goal motivation and goal progress of university students. Autonomous goal motivation was positively associated with task-oriented coping, which predicted greater goal progress during midterm exams (Study 1, N=702) and at the end of the semester in a different sample (Study 2, N=167). Controlled goal motivation was associated with greater disengagement-oriented coping (Study 1 and Study 2) and lesser use of task-oriented coping (Study 2), which reduced goal progress. These results held up after controlling for perceived stress (Study 2). Our findings highlight the importance of coping in the “inception-to-attainment” goal process because autonomous goal motivation indirectly rather than directly predicts goal progress of university students through their usage of task-oriented coping.

Why Doomsday Arguments are Better than Simulation Arguments

Inspired by anthropic reasoning behind Doomsday arguments, Nick Bostrom's Simulation Argument says: people who think advanced civilisations would run many fully‐conscious simulated minds should also think they're probably simulated minds themselves. However, Bostrom's conclusions can (and should) be resisted, especially by sympathisers with Doomsday or anthropic reasoning. This paper initially offers a posterior‐probabilistic ‘Doomsday lottery’ argument against Bostrom's conclusions. Suggestions are then offered for deriving anti‐simulation conclusions using weaker assumptions. Anti‐simulation arguments herein use more (epistemically and metaphysically) robust reference classes than Bostrom's argument, require no Principles of Indifference, abide better by the total evidence requirement, and yet use empirically plausible priors and likelihoods. However, while Doomsday arguments are probabilistically, epistemically and metaphysically stronger than the Simulation Argument, anthropic reasoning can (and should) refrain from embracing either.     

Meta‐Analysis of Integrated Primary and Behavioral Health Care Interventions for Treating Substance Use Among Adults

This meta‐analysis detected low effects in reducing substance use (Hedges's g = –0.11) in favor of using integrated primary and behavioral health care (IPBH) compared with treatment‐as‐usual approaches for adult patients with substance use. The impact of IPBH was limited.     

The influence of acceptance goals on self‐presentational efforts

The current work examined whether self‐presentational efforts are influenced differently when people hold a goal to establish, maintain or repair an interpersonal connection. Results supported the counterintuitive prediction that participants with a repair goal would convey a less favourably oriented persona (e.g. less friendly, less similar and less genuine) compared to those with an establish or maintain goal. The efforts of repair goal participants were also perceived as less effective. The analysis also showed that certain self‐presentation dimensions (i.e. friendliness, genuineness and similarity) mediated the relationship between acceptance goals and perceived effectiveness. The findings extend and contribute to the self‐presentation and belongingness literatures.
